A student wrote a proof about the product of two rational numbers: 1. Let 3 = and let y = à, where a and c are defined to be integers, and b and d are nonzero
integers.
2. By substitution, ry =
3. By applying the closure property of integers and nonzero integers on multiplication, ac is an
integer and bd is a nonzero integer.
What conclusion can the student now make about the product ty?

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
